RufasGate is a combination of the Portal and Sokoban games. Using stargate terminology, there are Zero Point Modules (ZPMs) that power the portal guns, which in turn create the two ends of a temporary and short range wormhole, a shortcut through space-time, that allows obstacles to be bypassed. In order to empower the portal guns, all cylindrical ZPMs must be bumped onto their base receptacles. There are currently only four levels, and no way to save a game. RufasGate is also a testbed for learning/illustrating various modern OpenGL techniques including cubemaps, water reflections, sound, and glsl shader capabilities. For anyone planning to use SDL2, it illustrates key-mapping, to get improved keyboard responsiveness from SDL. It supports laptops and high DPI Mac Retina displays.
